I need to loss min. 150 bytes of dynamic memory PLEASE HELP

Projects Programming
1

Hello, I'm programming a calculator with oled display and IR remote (using lightIRRecv).
I need around 350 bytes of dynamic memory (I'm using ARDUINO UNO) to get IR and OLED to work.

/////////////////////////////////////////

Here is memory usage

Sketch uses 24876 bytes (77%) of program storage space. Maximum is 32256 bytes.
Global variables use 1786 bytes (87%) of dynamic memory, leaving 262 bytes for local variables. Maximum is 2048 bytes.
:red_circle: Low memory available, stability problems may occur.

==========================

Here is the code (it's so long) 
#include <Wire.h>
#include <U8g2lib.h>
#include "lightIRRecv.h"

#define ir 3

Is there a reason why you did not use the drawBitmap() function from the library ?

Because I need to print mirrored animation.

How does the compiler know how much dynamic memory is used by global variables?

Does the compiler allocate copies in RAM?

I don't know how but I'm using ARDUINO IDE 1.8.19

The Arduino Uno is not really suitable for the u8g2 library. The u8x8 is for the Arduino Uno.
My suggestion is to use a board with more memory (for example a ESP32) or use the u8x8.

Can I also buy Arduino Mega?
Because it has more pins and I can connect an TFT touchscreen in past.

Yes, but they are expensive :moneybag:
The Raspberry Pi Pico and the ESP32 are cheap and have so much more.

But so much less pins :confused:

Looking at your "posted code" oops it disappeared. Try using the "F" macro. Example: Serial.print("Hello"); use Serial.print(F(:Hello");, that should save you about 5 bytes of ram as the message is stored in program memory. As I understand it when C start begins it copies all the messages and other data into RAM before your program is started. That memory is permanently allocated until it is reset. You can also print from EEPROM or external memory such as FRAM.

Look at the Teensy. Fast, loads of RAM and some of them have a lot of pins too.
